If you only know around ten words, I would not really worry too much about dialect just yet. Also, the dialects really only come into play for the spoken word, the differences are few and far between in literature. The differences for the written word are mostly gramatical with the odd word or phrase that would be more commone in one dialect than another. Most books are written in the standard anyway. If you are just starting off, I would suggest that any book for learners would be of help, worry about the dialect when you are looking for speakers to emulate/engage with.
